Description

La présente invention concerne une cuve de fermentation ou macération utilisée dans le domaine agro-alimentaire pour la fermentation ou macération de raisins.The present invention relates to a fermentation or maceration tank used in the food industry for the fermentation or maceration of grapes.

Les cuves se présentent traditionnellement sous forme de fûts métallique ou en matière plastique dressés verticalement. Le vidage de ces cuves nécessite le retrait des matières solides égouttées, séparées des jus liquides.The tanks are traditionally in the form of metal or plastic drums erected vertically. Emptying these tanks requires the removal of the drained solids, separated from the liquid juices.

Pour les évacuer de la cuve, on réalise généralement une ouverture dans la partie inférieure permettant d'introduire un outil pour rassembler les dépôts et les retirer.To evacuate them from the tank, an opening is generally made in the lower part making it possible to introduce a tool for collecting the deposits and removing them.

On a également proposé dans l'art antérieur d'équiper la partie inférieure de la cuve avec une pale d'un diamètre sensiblement égal à celui de la cuve entrainée en rotation par un moteur électrique fixé sur le fond de la cuve.It has also been proposed in the prior art to equip the lower part of the tank with a blade of a diameter substantially equal to that of the tank driven in rotation by an electric motor fixed on the bottom of the tank.

Lorsque la cuve est vidée du liquide, on met la pale en rotation à faible vitesse afin de rassember les dépôts solides et à forcer leur évacutation par un orifice pratiqué dans le fond de la cuve.When the tank is emptied of the liquid, the blade is rotated at low speed in order to collect the solid deposits and to force their evacuation through an orifice made in the bottom of the tank.

Le profil des pales est choisi de façon à concentrer les dépôts dans un anneau de balayage passant par l'orifice d'évacuation.The profile of the blades is chosen so as to concentrate the deposits in a scanning ring passing through the discharge orifice.

L'étanchéité du passage de l'axe moteur est toutefois difficile à réaliser. De plus, les cuves équipées de la sorte présentent un investissement et un coût d'entretien importants pour un producteur utilisant plusieurs cuves.Sealing the passage of the motor axis is however difficult to achieve. In addition, tanks equipped in this way present a significant investment and maintenance cost for a producer using several tanks.

La cuve selon la présente invention remédie à ces inconvénients. Elle comporte, en effet, dans sa partie inférieure des moyens permettant d'introduire un extracteur mobile pour les opérations de vidage. Bien sur, le même extracteur peut être utilisé pour plusieurs cuves. Il comporte un bras portant une pale entrainée en rotation par un bloc moteur constitué par un moteur électrique et un réducteur. La transmission s'effectue par une chaine ou un arbre de transmission. Le bras est monté sur un chariot et sa hauteur est variable.The tank according to the present invention overcomes these drawbacks. It comprises, in fact, in its lower part means making it possible to introduce a mobile extractor for emptying operations. Of course, the same extractor can be used for several tanks. It comprises an arm carrying a blade driven in rotation by an engine block constituted by an electric motor and a reduction gear. Transmission takes place via a chain or a transmission shaft. The arm is mounted on a carriage and its height is variable.

Le bras et la pale sont introduits dans la cuve après vidange du liquide par une ouverture latérale réalisée dans la partie inférieure. Lors de l'introduction, la pale est bloquée en position parallèle au bras. La cuve comporte un fond prolongé vers le bas par un caisson parallélépipédique disposé symétriquement au diamètre du fond.The arm and the blade are introduced into the tank after the liquid has been drained through a lateral opening made in the lower part. During introduction, the blade is locked in position parallel to the arm. The tank has a bottom extended downwards by a parallelepipedic box arranged symmetrically to the diameter of the bottom.

Ce caisson permet l'introduction du bras en vue de l'extraction des dépôts solides. Il comporte des moyens de guidage coopérant avec la paroi horizontale supérieure du bras réalisant une plaque d'étanchéité pour le fond de la cuve.This box allows the introduction of the arm for the extraction of solid deposits. It includes guide means cooperating with the wall horizontal upper arm making a sealing plate for the bottom of the tank.

Lors de la fermentation ou macération, l'ouverture latérale de la cuve communiquant avec le caisson est fermée par une porte d'extraction étanche.During fermentation or maceration, the side opening of the tank communicating with the casing is closed by a sealed extraction door.

La fente réalisée dans le fond de la cuve au niveau du caisson est recouverte d'une grille afin d'empêcher les dépôts solides de pénétrer dans le caisson.The slot made in the bottom of the tank at the level of the box is covered with a grid to prevent solid deposits from entering the box.

Lorsque la fermentation ou macération est achevée, le liquide est extrait par l'intermédiaire d'un orifice pratiqué dans le fond du caisson. La porte d'extraction est alors ouverte pour l'introduction du bras d'extraction et de la pale. La grille est ensuite retirée par la porte en la faisant glisser et la pale est mise en rotation. La pale dont le profil épouse le fond de la cuve, est mise en rotation afin de rassembler les dépôts et à les évacuer par un orifice d'évacuation des dépôts pratiqué dans le fond de la cuve. La plaque d'étanchéité empêche les dépôts de pénétrer dans le caisson. La pale, remise en position parallèle au bras, est ensuite retirée et l'extracteur devient disponible pour le vidage d'une nouvelle cuve.When fermentation or maceration is complete, the liquid is extracted through an opening in the bottom of the box. The extraction door is then opened for the introduction of the extraction arm and the blade. The grid is then removed by the door by sliding it and the blade is rotated. The blade, the profile of which conforms to the bottom of the tank, is rotated in order to collect the deposits and to evacuate them through an orifice for removing deposits formed in the bottom of the tank. The sealing plate prevents deposits from entering the box. The blade, returned to the position parallel to the arm, is then removed and the extractor becomes available for emptying a new tank.

D'autres avantages et formes de réalisation ressortiront mieux de la description illustrée par les dessins suivants :

  • la figure 1 représente une vue de face de la cuve avec le bras de l'extracteur en place,
  • la figure 2 représente une vue en plan du fond de cuve et
  • les figures 3 et 4 représentent une vue de l'extracteur.
Other advantages and embodiments will emerge more clearly from the description illustrated by the following drawings:
  • FIG. 1 represents a front view of the tank with the extractor arm in place,
  • FIG. 2 represents a plan view of the bottom of the tank and
  • Figures 3 and 4 show a view of the extractor.

La cuve représentée selon la figure 1 ou la figure 2 comporte un fût vertical (1) de préférence cylindrique avec un fond (2) prolongé par un caisson (3). Dans la paertie inférieure de la cuve, une ouverture latérale (4) communique avec le caisson (3). L'ouverture latérale peut être fermée hermétiquement par une porte (5) comportant des moyens de vérrouillage (6) de type connu. Le caisson (3) comporte un orifice d'évacuation des liquides (7) commandé par un robinet et des glissières de guidage (8), disposés à une hauteur légèrement inférieure au fond (2) de la cuve.The tank shown according to Figure 1 or Figure 2 comprises a vertical barrel (1) preferably cylindrical with a bottom (2) extended by a box (3). In the lower part of the tank, a lateral opening (4) communicates with the box (3). The lateral opening can be hermetically closed by a door (5) comprising locking means (6) of known type. The box (3) has a liquid discharge opening (7) controlled by a tap and guide slides (8), disposed at a height slightly lower than the bottom (2) of the tank.

La section du caisson (3) peut être rectangulaire ou semi-circulaire. Ses dimensions doivent être suffisantes pour pouvoir recevoir le bras de l'extracteur et sa partie inférieure doit présenter une concavité suffisante pour permettre l'évacuation des liquides par l'orifice (7).The section of the box (3) can be rectangular or semi-circular. Its dimensions must be sufficient to be able to receive the extractor arm and its lower part must have a sufficient concavity to allow the evacuation of liquids through the orifice (7).

La partie supérieure du caisson est recouverte pendant la fermentation ou macération par une grille (10) empêchant les dépôts solides de pénétrer dans le caisson. Elle peut-être réalisée en métal inoxydable ou en matière plastique et peut être du type à perforations du 2,5 mm de large par 20 mm environ de longueur ou bien par lattes parallèles juxtaposées dans le sens longitudinal du caisson.The upper part of the casing is covered during fermentation or maceration by a grid (10) preventing solid deposits from entering in the box. It can be made of stainless metal or plastic and can be of the 2.5 mm wide by 20 mm long perforation type or by parallel slats juxtaposed in the longitudinal direction of the box.

La grille (10) peut-être introduite au-dessus du caisson (3) ou retirée longitudinalement grâce à des glissières (11). Un orifice d'évacuation des dépots solides (12) est aménagé dans le fond (2) de la cuve et demeure obturé pendant la fermentation ou macération par une porte étanche (5) de type connu.The grid (10) can be introduced above the box (3) or removed longitudinally by means of slides (11). A hole for evacuation of solid deposits (12) is arranged in the bottom (2) of the tank and remains closed during fermentation or maceration by a sealed door (5) of known type.

L'extracteur représenté sur la figure 3 comporte un bras (13) constitué d'une plaque d'étanchéité (14) et de parois latérales (15, 16 et 17). Le bras (13) est fixé sur un châssis (18) réglable en hauteur par des moyens connus, par exemple une crémaillère.The extractor shown in Figure 3 has an arm (13) consisting of a sealing plate (14) and side walls (15, 16 and 17). The arm (13) is fixed to a frame (18) adjustable in height by known means, for example a rack.

L'extracteur représenté sur la figure 4 est une variante du précédent dans lequel l'orifice d'évacuation (12) est supprimé sur le fond (2) de la cuve et est remplacé sur la plaque d'étanchéïté (14) et vers le caisson (3) par une ouverture (28); les matières solides tombant dans cette ouverture sont poussées par une vis sans fin (29), elle-même actionnée par un motoréducteur (31) et évacuées par un orifice (30) donnant sur l'extérieur. Dans cette variante, la transmission (24) aura la longueur intérieure du caisson (3) afin de laisser passer la vis sans fin (29).The extractor represented in FIG. 4 is a variant of the previous one in which the evacuation orifice (12) is removed on the bottom (2) of the tank and is replaced on the sealing plate (14) and towards the box (3) through an opening (28); the solid materials falling into this opening are pushed by an endless screw (29), itself actuated by a geared motor (31) and discharged through an orifice (30) leading to the outside. In this variant, the transmission (24) will have the inside length of the box (3) in order to let the worm (29) pass.

Le châssis (18) comporte un socle (19) monté sur des roulettes pivotantes (20).The chassis (18) has a base (19) mounted on swivel casters (20).

Le châssis (18) supporte également un bloc moteur constitué d'un moteur électrique (21) et d'un réducteur (22) entrainant la pale (23) à une vitesse comprise entre 1 tour/minute et 20 tours/minute par l'intermédiaire d'une transmission (24) constituée par une chaine ou un arbre de transmission. La pale (23) est fixée sur un axe vertical (25).The chassis (18) also supports an engine block consisting of an electric motor (21) and a reduction gear (22) driving the blade (23) at a speed of between 1 revolution / minute and 20 revolutions / minute per via a transmission (24) consisting of a chain or a transmission shaft. The blade (23) is fixed on a vertical axis (25).

La plaque d'étanchéïté (14) s'adapte avec précision avec les glissières latérales (8) du caisson (3) de façon à empêcher les dépôts solides de pénétrer dans le caisson.The sealing plate (14) fits precisely with the lateral guides (8) of the box (3) so as to prevent solid deposits from entering the box.

Le profil de la pale peut être droit ou peut présenter une concavité orientée vers le sens de rotation de façon à concentrer les dépôts dans un anneau de balayage passant au-dessus de l'orifice d'évacuation des dépôts solides (12). Le diamètre de la pale est sensiblement égal au diamètre de la cuve (1). Elle est constituée d'éléments métalliques. Ces tranches (26 et 27) peuvent être recouvertes d'un bandeau déformable de type caoutchouc permettant d'épouser les irrégularités présentes à la surface de la cuve et du fond (2).The profile of the blade may be straight or may have a concavity oriented towards the direction of rotation so as to concentrate the deposits in a scanning ring passing above the orifice for removing solid deposits (12). The diameter of the blade is substantially equal to the diameter of the tank (1). It is made up of metallic elements. These sections (26 and 27) can be covered with a deformable strip of the type rubber allowing to marry the irregularities present on the surface of the tank and the bottom (2).

Selon une variante, l'axe (25) est muni d'un détecteur de position permettant de bloquer la pale (23) dans une position parallèle au bras (13). Ce détecteur peut être électromagnétique ou optoélectronique et il commande l'arrêt du moteur électrique lorsque l'utilisateur souhaite retirer l'extracteur de la cuve.Alternatively, the axis (25) is provided with a position detector for locking the blade (23) in a position parallel to the arm (13). This detector can be electromagnetic or optoelectronic and it controls the stopping of the electric motor when the user wishes to remove the extractor from the tank.

Selon une autre variante, le socle de l'extracteur supporte un récipient permettant de recueillir les dépôts solides évacués par l'orifice (12).According to another variant, the base of the extractor supports a container making it possible to collect the solid deposits discharged through the orifice (12).

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés ici mais on peut y apporter de nombreuses modifications sans pour cela sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments described and shown here, but many modifications can be made without departing from the scope of the invention.
